PUSH-BUTTON APPARATUS.

Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed October 4, 1907. Serial No. 395,954.

To all whom it may concern:

Be it known that l', RALPH I). Bunk, a citizen ot' the United States,residing in the city of New York, borough of Brooklyn, county of Kings,and State of New York, have invented a certain lowing is aspecilica'tion.

This invention is a push-button apparatus i speciallyesigned to generatean electric current by which may be operated various f forms ofelectrical translating devices, such as call bells, door locks, `iraslighters, and

other apparatus requiring electric current tor their operation.

My object is to dispense with a battery,

and more particularly with the dry batteries now so commonly employed inelectrical apparatus of the kinds above mentioned.

The disadvantages attending the use of a battery are numerous, such asthe formation of a short circuit at the` liiattery, the corrosion oi thewires and the contacts, renewal of the battery elements, and the expenseand delay oi replacing a worn out battery by a. new one.

In the present. invention, a reciprocating push button is associatedwith means for directly operating the armature of a compact magnetogenerator, whereby the operation of said push button generates in themaor ieto machine'a current oi 'electric energy iviieli is utilized forthe operation of an appropriate trauslatimr device. the latter beingr incircuit with lsaid magneto ,grencratoixl In the accompanying, drawings lhave illustrated one p aetical embodiment of the invention, but. tlu`construction shown therein is to bc understood as illustrative, only,and not as defining' the limits of the invention.

F igure 1 is a. view showing my push button apparatus in connection witha trans- 5 latin;r device in `the form of avc-all bell, a part ot saidpush button' apparatus being.; i

shown in elevation and another part in vertical section. Fig. 2 is a.vertical longitudinal section on an enlarged scale through the pushbutton apparatus, certain parts being in elevation. Fig. 3 is a detailview illustrating the nut. in a free or idleposition on the returnmovement. of the reciprocating member of push button apparatus.

A frame or casing of any suitable cliaraeter is employed for supportingthe operatnew and useful: Push-Button Apparatus, of which the iol- I '1stop pin. e.

iunparts and magneto of my push button apparatus. Said frame, A, isshown as liavmp,I a iace plate. A', and a pillar plate, A,y

but it will be uiLdcrs-tood that the particular form oi frame or casingis not a material part of the invention. Face plate, A', is shown ashaving` a bowl shaped socket membei', c, the inner part of which istubular at a to serve as a guide for reciprocating member or pushbutton, B.

The reciprocating member, B, is provided with a chamber, I), in which ispositioned a ratchet nut, (l. and into said chamber extends the forwardpart of espiral o erating spindle. D, said spindle being in a inementwith the' member, B. The rear part of spindle, D, is journaled in pillarlate, A2, whereas the front part of said spin le is supported inchambered member, B. Said i chambered member is provided with alo1igitudinal groove, e. into which extends a stop ,pin or stud` o,thclatter being fixed to the tubular part, a. of iface plate, A. The re-:iprocating member, B, is free to travel in the tubular guide, a', andit is limited to rectilinear movement therein by the screw or pin, o',working in longitudinal groove, e,

tary movement, but is free to travel in the direction of its length. Theends of groove, c. in member, B, are closed, so Athat stop pin, 1 c',will engage with said closed ends, Whereby the inward movement ofmember, B, unl der the pressure of the hand is arrested by Said stop pinserves to arrest, f acts against the rear closed end of member, l B,under the action ot' a retractor herein i shown as a coiled spring, E.Said spring is l represented as fitting loosely around spiral l spindle,D, and the front end of the spring acts against the Arear closed end ofmember, B, for the purpose of holding it normally in a position readyfor operation, wherein the front part of said member, B, occupies the I,chamber of socket member, a. The magneto generat'tir is of any usual or.l preferred construction, and it is shown as being supported on frame orcasing, A. The i permanent magnet, f, of said magneto generator, F, isfixed to pillar plat/e, A2, whereas i the shaft., f2, of armature, f',is journaled in appropriate bearings on pillar plate, A2.

The spiral rotatory spindle, D, is mounted in -pillar plate and recirocatinp, member to ,turn freely therein, am said spindle is held fromendwise movement b any suitable l nut, C, thus piiov'iding a compact andsimple means, such as strap, d, fixe to pillar plate, A, and engagingwith one end of spindle, D. On said spindle is rigidly secured a drivinggear, g, which meshes with a driven gear, g', the latter bein secured toshaft, 2, of armature, f', where y gears, g, g', irectly connectspindle, D, with armature of ma eto generator.

e nut, C, is held conned loosely within chamber, b, of reciprocatingmember, B, and said nut is rovided on-one of its faces with ratchet teeti, c, shown more clearly in Fig. 3. The reciprocating member, B, isrovided with interior ratchet teeth, b', 'w ich are in opposing relationto ratchet teeth, c, of nut, (J, also shown in Fi 3.- When the member,B, is pressed inwarl the teeth, b', of said member enga e with teeth, eof nut',` C, thereby lookin said nut, C, to sind member, B, aridrestraining said nut from rotati in' within said chamber, b, during saidinward inlovernent of member, B. Said operation imparts rotary motion tospiral spindle, D, for the reason that nut, C, has a thread, or sectionof a thread, arranged to engage with the spiral portion of spind e, D.It follows that t e inward movement of member, B, and. nut, C,compresses sprin E at the same time spindle, D, is rotate anll gears, g,transmit the rotary motionw of said s in le to armature, f', of themagneto, w ereby, said magneto is o erated to generate an electriccurrent. hen pressure is removed from member, B, spring, E, forces saidmein'- ber back to its normal position, but during this return movementnut, C, is disengaged from the ratchet face, b', of said member, B,whereby said nut, C, is -free to rotate, idl on spiral spindle, D, whenit is carried bac to its normal osition within chamber, b, of member, B.his allows spindle, D, to remain at rest and hence the magneto will notbe o erated during the return movement of mem er, B, and its associatedparts.

In Fig.' 1 the translatin device ris rep? resented 1n the form of a ca lbell, G, which is included in a circuit, h, h', with the magneto, F. Itwill be understood, however, that other forms of translating devices maybe used in connection with the push button apparatus. i

he push button or reciprocating member,

B, may be of any suitable construction, but, as shown in Figs. 2 and 3,saidpush button consists of two parts, b2, b3, the latter having aninternal thread and the former having a male thread whereby the two artsmay be screwedtogether detachably, t us enabling easy access to beobtained to chamber, b, for lacing nut, C, therein, or removing itthereom. The male threaded part of the member is rovided on its innerextremityT or face with t e ratchet' teeth, b', with which are adaptedto engage the ratchet teeth, c, of

construction of the ush button with which co erates said ratc et nut.
